IMPROVED APPARATUS FOR GARBURETTING AIR.

TO ALL WHOM IT MAY CONCERN:

Be it known that 'we, JOSEPH H. SPRINGER and JOHN G. llIODONALD, both of the'city and ma of Philadelphia, in the State of Pennsylvania, have invented a new and useful improvement in Carburetting Air; of which improvement the following is a full, clear, and exact description, reference being bad to the accompanying drawings, which make part of this specification, and in which- Figure 1 represents a plan or top view of an apparatus embracing our improvement, and

Figure '2 a vertical longitudinal section through the same.

Figure 3 shows a side elevation, and also an end view of one of the air-tubes.

It is the object of our invention to produce a steady, brilliant light from gasoline, or other analogous hydrocarbons, bya cheap, simple, efiective, and portable apparatus for carburetting air.

In the accompanying drawings, an air-chamber, A, is shown as fitting over an oil-chamber, B, from which it is separated bya diaphragm, G, through which a series of tubes, D, passes. These'tubes are openat their upper ends, and' project above the diaphragm a short distance. The lower ends of these tubes extend nearly to the bottom of the oil-chamber B, and have numerous's mallslits, (I, cut in them. The joint between the two chambers is rendered gas-tight by suitable packing, and secured by screws c. A tank, E, is separated from the chamber 13 by a. partition, 6, which is pcrfora'ted with a row of holes, a. A division-plate, F, is conuectedwith the partition below these holes, and extends upward nearly to the top of the tank, thus forming a waste-box, as will be presently more fully described. A pipe, G, provided with a suitable stop-cock, 9, leads to the burners H H, which may of coursebe located wherever desired, and connected with the apparatus by suitable pipes.

The operation is as follows: 1 The oil-chamberB isfilled about half full of oil, through its openingb; The chamber A is also -filled with oil, to the level of the top of the tubes D, through the opening a. Air is now forced into this chamber through thesame opening, and mingles with the vapor arising from the oil above the diaphragm. The air then passes down through the tubes and escapes through the slits d' bubbling upthrough the oil in the lower chamber B. Wehave found that in nsing ope-n tubes large bubbles are formed, the constant bursting of whichi'reuders the flame 'unsteady,-but by subdividing the jet we not only render the flame steady, but promote the vaporization of the fluid. The chamber B being only partially filled, its upper portion forms a mixing-chamber for the air and gas, which finally pass into the tank E through the openings e. The divisionplate F acts as a shield, against which the spray strikes, and thus prevents oil from being carried into the'tauk E. Anyoil thus carried through the holes 0 will be arrested by the shield F and flow back through the holes 0 into the 'tank B, so that the gas rising above the shield, as shown by the arrow, will be freed from this spray, and consequently be more pure.

What we claim as our invention, and desire tosecure by LcttersPatent, isr 1. The-perforated air-tubes, constructed, arranged, and operating as described.

2. The combination oftwo carburetting-chambers, separated by a diaphragm, traversed by air-tubes, substantially in the manner described.

3. The combination of the oil-chambers and tank with the perforations e and shield lib arranged and operating as and for the purpose described.

In testimony whereof we have hereunto subscribed our names.
